[plug] Debian Sarge + Exim4 + Smarthost relay

[Michael Hunt]

Hi ya all,

I have just noticed that over the last couple of days my ever reliable
sarge + exim4 + Arachnet as a smarthost mail server setup is now become
not so reliable. 

/var/log/exim4/mainlog lists errors like the following :-

SMTP error from remote mailer after STARTTLS: host mx1.arach.net.au [203.30.44.129]:
454 TLS missing certificate: error:0200100D:system library:fopen:Permission denied (#4.3.0):

I'm assuming that because of the '454 TLS missing certificate' that
sometime during the setting up the connection to relay one end is trying
to authenticate the connection and fails. Since I currently don't need
to enter authentication details in evolution in order to use Arachnet's
smtp mail server, I'm assuming that the problem is at my end.

Some googling turned up some info that Debian's exim4 now supports TLS
by default and that my end probably hasn't had appropriate certificates
setup. So far I have always setup exim4 using debconf and filling in the
boxes and haven't had much experience with exim's conf files. If anyone
could point me to the appropriate changes for switching of TLS or tell
me how to generate certificates I would much appreciate the assistance.

Of course if you think I am barking up the wrong tree then telling me so
would also be 'very' helpful too :-)
